The First Of Two Cold Fronts....

The 500MB pattern is fairly amplified for the end of August, isn't it? For a month that has struggled to maintain heat outside of Texas, Florida and sections of the West, the passage of yet another polar intrusion with a pronounced drop in temperature, especially at night, will not come as a surprise. But like the previous cooldown, heat will remain west of the Continental Divide and below Interstate 20. In the energy business, this incoming domain is known as a "demand killer", with the need to cool homes and businesses reduced as readings will be below normal to the east and north of ridging. At 72 hours, see that Texas is still under a heat ridge, as is Florida.

The rather strange monsoon of 2025, with its history of impacts in Texas and along the western slopes of the Rocky Mountains will expand again in the near term, and could last as much as the next ten days. In time the moist mTw regime will be suppressed into Mexico, most likely in the second week of September when this episode finishes and drier air resumes control. The vertical velocity and lifted index predictions are telling me that a stationary front in between the Interstate 10 and 20 corridors may interact with a tropical wave in the near term and medium range, so the QPF totals posted in this section may be underdone. The most obvious severe weather potential is in the center of the nation on Sunday, perhaps reaching into North Texas and Arkansas on Monday.
